Item 56374        

Operation

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the 
beginning of this document including all text under subheadings therein 
before set up or use of this product.

WARNING!

  Use as matched pair to support one end of a vehicle only.

Supporting a Vehicle

1.  Make sure the vehicle does not exceed 

the capacity of the Jack Stands.

WARNING!  Weight must be evenly 
distributed between each Jack 
Stand. You must evenly distribute 
the weight

 

or the Jack Stands may 

fail, causing severe injury or death.

 

 

Only apply the load vertically.

WARNING!

  If a vehicle drops on the 

Jack Stands (even if it is under the 
weight capacity limit), the principle 
of “dynamic loading” takes effect.  
The force of the weight falling may cause 
the Jack Stands to fail.  A vehicle weighing 
much less than the Jack capacity may cause 
the Jack Stands to fail if dropped on them.

Note:

  Do not move the Handle when the 

Jack Stands are supporting a vehicle.  The 
shear pin is designed to shear in the event 
the user attempts to move the Handle while 
supporting weight.  If the pin shears, do not 
use the Jack Stands again until the shear 
pin is replaced by a qualified technician.

2.  Examine Jack Stands for cracks or 

damage before each use.  

Do not 

use if even a minor crack, bend, 
or other damage/deformation 
appears.  Discard Jack Stand 
if damaged or deformed.

3.  Raise the Handle on each Jack Stand 

and completely lower the Post.

4.  Block the tires that will 

remain on the ground.

5.  Following the instructions in your 

floor jack manual, raise your 
vehicle to just above the minimum 
height of your Jack Stands.

6.  Move Jack Stands to manufacturer-

recommended vehicle support locations.   
Place the Stands at the same point 
on each side of the vehicle.  

7.  Move the Handle up, and raise the Jack 

Stands until they are just below the jack 
contact point on the vehicle.  Center 
the load on the Saddle of the Post.  

8.  Release the Handle so that ratchet 

catches on the Pawl. Gently lower 
the vehicle with the floor jack.  It 
may drop down a very small amount 
until the ratchet catches on the 
Pawl.  Repeat on other side.

WARNING!

  Set both the 

Jack Stands to the same height.

7.  Determine if the vehicle is stable. 

If not, raise the vehicle and 
reposition the Jack Stands.

8.  Remove floor jack.
